摘要
A method for forming a blanked piece from a material, where the blanked piece includes a production area having a through hole and at least one caulking and connection area protruding inside the through hole. The method includes forming a blanking hole in the material in a prescribed outline, placing a guide member in the through hole, where the guide member has an abutting part contacting a protrusion of the material formed along the outline of the blanking hole. The method further includes cutting and separating the material to blank or stamp out downward the caulking and connection area, pushing back the caulking and connection area, and temporarily connecting the caulking and connection area to the material; and blanking or stamping an outer configuration of the product area from the material to which the caulking and connection area is temporarily connected.
